次に、ワイヤハーネス２を車体に配索すべく、上記構造のプロテクタ１０を電線束１に装着して車体に固定する手順の一例について説明する。   Next, an example of a procedure for attaching the protector 10 having the above structure to the wire bundle 1 and fixing it to the vehicle body in order to route the wire harness 2 to the vehicle body will be described.

まず、本体２０の収容部２３に電線束１を収容させる。このとき、電線束１の幹線１ａは、本体２０の両端から引き出し、電線束１の分岐線１ｂは、凹状部３８にそれぞれ収容させる。次に、幹線クランプ４１及び分岐線クランプ４３によって電線束１の幹線１ａ及び分岐線１ｂを仮保持する。   First, the wire bundle 1 is accommodated in the accommodating portion 23 of the main body 20. At this time, the trunk line 1a of the wire bundle 1 is pulled out from both ends of the main body 20, and the branch lines 1b of the wire bundle 1 are accommodated in the concave portions 38, respectively. Next, the trunk line 1 a and the branch line 1 b of the wire bundle 1 are temporarily held by the trunk line clamp 41 and the branch line clamp 43.

その後、本体２０に蓋体５０を被せるように装着する。このとき、蓋体５０の一方の突条部５２Ａを、一方の側壁部２２Ａとフランジ部２５との間の隙間Ｇに入り込ませる。そして、蓋体５０の一方の突条部５２Ａに形成された係合片５３を、本体２０の連結リブ２９の間へ挿し込む。すると、係合片５３の係合爪５４が係合孔２８に入り込み、この係合爪５４が係合孔２８の係合縁部２７に係止される。また、蓋体５０の他方の突条部５２Ｂの係合片５５を、本体２０の他方の側壁部２２Ｂの受け部３５に挿し込む。すると、係合片５５の係合爪５６が係合縁部３６に係止される。   Thereafter, the body 20 is mounted so as to cover the lid 50. At this time, one protrusion 52 </ b> A of the lid 50 enters the gap G between the one side wall 22 </ b> A and the flange portion 25. Then, the engagement piece 53 formed on one protrusion 52 </ b> A of the lid 50 is inserted between the connecting ribs 29 of the main body 20. Then, the engagement claw 54 of the engagement piece 53 enters the engagement hole 28, and the engagement claw 54 is locked to the engagement edge portion 27 of the engagement hole 28. Further, the engaging piece 55 of the other protrusion 52B of the lid 50 is inserted into the receiving portion 35 of the other side wall 22B of the main body 20. Then, the engaging claw 56 of the engaging piece 55 is locked to the engaging edge 36.

本体２０に蓋体５０を被せて装着することで、本体２０における収容部２３の上方開口部分が閉鎖されるとともに、凹状部３８が蓋体５０のカバー部５８で閉鎖される。これにより、電線束１にプロテクタ１０が装着される。   By attaching the lid 50 to the main body 20, the upper opening portion of the accommodating portion 23 in the main body 20 is closed, and the concave portion 38 is closed by the cover portion 58 of the lid 50. Thereby, the protector 10 is attached to the wire bundle 1.

電線束１にプロテクタ１０を装着したら、プロテクタ１０の本体２０の底部に形成された固定クランプ４５を車体の被取付部に形成された係止孔へ挿し込み、係止孔の縁部に係止させてプロテクタ１０を被取付部に固定する。これにより、電線束１にプロテクタ１０が装着されたワイヤハーネス２が車体の被取付部に配索される。   When the protector 10 is attached to the wire bundle 1, the fixed clamp 45 formed on the bottom of the main body 20 of the protector 10 is inserted into the locking hole formed in the mounted portion of the vehicle body and locked to the edge of the locking hole. Then, the protector 10 is fixed to the attached portion. Thereby, the wire harness 2 in which the protector 10 is attached to the wire bundle 1 is routed in the mounted portion of the vehicle body.

ところで、プロテクタ１０は、本体２０の一方の側壁部２２Ａ側が、長手方向に沿ってフランジ部２５を有することで、外面に凹凸が極力なくされている。したがって、このプロテクタ１０を車体の被取付部へ取り付ける際に、プロテクタ１０の周辺部品や構造物への引っ掛かりが抑制される。   By the way, as for the protector 10, the one side wall part 22A side of the main body 20 has the flange part 25 along a longitudinal direction, and the unevenness | corrugation is made into the outer surface as much as possible. Therefore, when the protector 10 is attached to the mounted portion of the vehicle body, the protector 10 is restrained from being caught on peripheral parts and structures.

また、電線束１が引っ張られることで、本体２０に対して蓋体５０が持ち上げられて外れる方向に外力が作用した際に、その外力が、本体２０の長手方向に沿って形成されたフランジ部２５によって分散されて受け止められることとなる。よって、局所的な外力の作用による破損等が抑制される。   Further, when the electric wire bundle 1 is pulled, when an external force is applied to the main body 20 in a direction in which the lid 50 is lifted and removed, the external force is formed along the longitudinal direction of the main body 20. 25 is distributed and received. Therefore, damage due to the action of local external force is suppressed.

以上、説明したように、本実施形態に係るプロテクタ１０によれば、本体２０の側壁部２２Ａと、この側壁部２２Ａの外面側に長手方向に沿って並行に延設されたフランジ部２５との間の隙間Ｇに蓋体５０の係合爪５４が挿し込まれると、フランジ部２５の下方に設けられた係合孔２８の係合縁部２７に係合片５３の係合爪５４が係止される。したがって、プロテクタの外面における凹凸を極力なくして見栄えを良くすることができるとともに、車体等の被取付部へ取り付ける際に、周辺部品や構造物への引っ掛かりによる破損を抑制できる。また、本体２０の収容部２３側への凹凸もなく、収容部２３への電線束１の収容作業を円滑に行うことができる。
しかも、例えば、収容部２３に収容された電線束１が引っ張られることで、本体２０に対して蓋体５０が持ち上げられて外れる方向に外力が作用した際に、その外力が、本体２０の長手方向に沿って形成されたフランジ部２５の全体で受け止められて分散されることとなる。よって、局所的な外力の作用による破損等を抑制できる。 As described above, according to the protector 10 according to the present embodiment, the side wall portion 22A of the main body 20 and the flange portion 25 extending in parallel along the longitudinal direction on the outer surface side of the side wall portion 22A.

Stopped. Therefore, it is possible to improve the appearance by minimizing the unevenness on the outer surface of the protector, and to suppress damage due to catching on peripheral parts and structures when attaching to the mounted portion such as the vehicle body. Moreover, there is no unevenness | corrugation to the accommodating part 23 side of the main body 20, and the accommodation operation | work of the electric wire bundle 1 to the accommodating part 23 can be performed smoothly.
Moreover, for example, when the electric wire bundle 1 accommodated in the accommodating portion 23 is pulled and an external force is applied to the main body 20 in a direction in which the lid 50 is lifted and removed, the external force is applied to the longitudinal direction of the main body 20. The entire flange portion 25 formed along the direction is received and dispersed. Therefore, damage due to the action of local external force can be suppressed.

また、本実施形態に係るプロテクタ１０によれば、本体２０の係合孔２８の両側部には、側壁部２２Ａとフランジ部２５とを連結する連結リブ２９が形成されている。これにより、係合爪５４を係止することで特に力が作用される係合孔２８の両側部を連結リブ２９によって補強することができ、より破損を抑制できる。   Further, according to the protector 10 according to the present embodiment, the connecting ribs 29 that connect the side wall portion 22 </ b> A and the flange portion 25 are formed on both side portions of the engagement hole 28 of the main body 20. Thereby, both sides of the engagement hole 28 to which a force is particularly applied by locking the engagement claw 54 can be reinforced by the connecting rib 29, and damage can be further suppressed.

また、本実施形態に係るプロテクタ１０によれば、フランジ部２５における係合爪５４の挿し込み方向前方側の縁部と側壁部２２Ａとが底板部２６によって連結されている。したがって、この底板部２６によってフランジ部２５の強度を高めることができるとともに、フランジ部２５に付与される外力を底板部２６によって本体２０に伝達させて分散させることができる。   Further, according to the protector 10 according to the present embodiment, the edge on the front side in the insertion direction of the engaging claw 54 in the flange portion 25 and the side wall portion 22 </ b> A are connected by the bottom plate portion 26. Therefore, the strength of the flange portion 25 can be increased by the bottom plate portion 26, and the external force applied to the flange portion 25 can be transmitted to the main body 20 by the bottom plate portion 26 and dispersed.
